Abstract: PURPOSE:To improve the measuring accuracy while reducing the measuring time by a calculation to determine the incoming direction of radio wave. CONSTITUTION:A quantized bearing waveform data 21 is memorized into a display memory 22. The memorized data is read out sequentially and expanded to a desired magnification to be indicated on a display 23. A cursor generation circuit 24 indicates a cursor line C crossing at the right angle to the azimuth on the screen of a display 23. The cursor line C is movable in the direction of the azimuth on the screen by operating an operation element of the circuit 24 and when a point (a) is specified in data 21, the position of the cursor line is read out with a cursor position reader 26 to be fed to a bearing inclination angle arithmetic unit 27, which obtains approximation of straight lines running between the point (a) and two or three bearing waveform data near it and likewise, a point (b) is specified to obtain approximation of straight lines running between the point and bearing waveform data. Data of both the straight lines are fed to an intersection computation unit 28 to determine the intersection. The data of the intersection is converted into an azimuth character data with a memory table made up of ROMs or the like and indicated as character on a display 23.

Filed: 1993-03-24
Abstract: PURPOSE:To prevent a malfunction of a current-differential type decision device which is caused by a transient current when a fault is generated, by providing high-pass filters cutting off the lower-frequency components than a predetermined frequency in first and second transducers. CONSTITUTION:In a monitor for a power equipment, a current-differential type decision device 25 is provided wherein the voltage signals outputted from a first transducer 23a and second transducers 24a, 24b are inputted and the existence of the generation of a fault is decided based on the difference between both these voltage signals. Especially, high-pass filters which cut off the lower-frequency components than a predetermined frequency are provided respectively in the first transducer 23a and the second transducers 24a, 24b. When a transient primary current caused by the generation of the fault flows through a first current transformer 21a, the error caused by a transient DC component is generated in the difference between the voltage signals outputted from the first transducer 23a and the second transducers 24a, 24b. But, by virtue of the actions of the high-pass filters, the difference between those voltage signals can be made zero. Therefore, even when transient current flows through respective electric path system by a fault, the malfunction of the a current-differential type decision device 25 can be prevented.
